Are Baby Animals Less Appetizing? Tenderness toward Baby Animals and Appetite for Meat

Three studies investigated whether thoughts and feelings generated by baby animals might oppose appetite for meat. A prestudy established babyness as an important factor predicting moral concern for farmed animals. Study 1 showed that presenting images of baby animals, versus adult animals, as the source of meat reduced appetite for meat, but this effect was weak and found exclusively among women. Study 2 replicated and extended study 1 using a larger sample and two new animal sources. Study 3 included a no animal comparison condition, and found greatest levels of reduced appetite for meat when the meat source was presented as a baby animal, as opposed to an adult animal or with no visual indication of the animal source. A meta-analysis of the results using Bayes factors revealed considerable cumulative evidence in favor of the hypothesis that images of baby animals temporarily reduce women’s appetite for meat. In contrast, the evidence for men was less strong. Our results highlight a tension within some omnivores between caring for baby animals and appetite for meat.     

Ponies Out of Place? Wild Animals,Wilderness and Environmental Governance

Powerful institutions in Australia regularly depict the continent as overrun with fauna variously described as ‘feral’, ‘vermin’, ‘alien’ and ‘invasive’. This paper addresses the issue of ‘animal matter out of place’ through the ethnographic analysis of a long-running conflict over ‘feral’ ponies in Coffin Bay National Park, South Australia. As the Department of Environment and Heritage manoeuvred to eliminate this ‘alien’ presence from the ‘pristine’ landscape of the Coffin Bay Peninsula, local residents argued that the herd was a product of this ecological niche and should remain in its ‘natural’ home. The trajectory of the conflict suggests that the expansion of environmental governance from centre to periphery is by no means as predictable and inevitable as is often anticipated.1     

“What Do Animals Mean to You?”: Naming and Relating to Nonhuman Animals

ABSTRACT

This article presents an analysis of data from over 200 accounts of, and responses to questions about, how animals feature in people's lives. The accounts were generated by a Mass Observation Project (MOP) directive on “Animals and Humans.” The MOP, based at a UK university, sends out two or three directives a year, asking correspondents to write in response to a series of questions and prompts. The “Animals and humans” directive began with the question, “What do animals mean to you?” followed by a range of prompts about respondents' experiences of animals. The paper is specifically concerned with issues of how language both reflects and contributes to typologies of living creatures. It presents a qualitative analysis of some of the themes that emerged from responses to the directive, as well as a more quantitative analysis of the words chosen by respondents to denote different kinds of animals. Using these different methodological approaches, it focuses on how moral ambiguity is expressed and the ways in which categories and meanings shift depending on linguistic context. These methods complement each other, with the computer-assisted linguistic analysis providing a different and more quantitative method of revealing aspects of people's values, attitudes, and assumptions as they report on the role of animals in their lives. Overall, the paper shows how a corpus linguistic analysis can demonstrate the permeability of categories and boundaries, and the moral ambiguity toward animals that is revealed in the way language is used.     

“Animals Like Us”: Identifying with Nonhuman Animals and Support for Nonhuman Animal Rights

While anthropomorphizing nonhuman animals has been shown to increase identification with them and, by extension, concern for their wellbeing, little research has directly tested whether identifying with nonhuman animals is similarly associated with concern for their wellbeing. We tested hypotheses related to this premise across three cross-sectional studies. In study 1 (n = 224), we tested the hypothesis that therians—a group of people who self-identify with nonhuman animals, show greater concern for nonhuman animal rights than non-therian furries—people with a fan-like interest in media featuring anthropomorphized animal characters. In study 2 (n = 206), we further tested this hypothesis using implicit and explicit measures of identification with nonhuman animals to predict behavioral intentions to support nonhuman animal rights. In study 3 (n = 182), we tested the generalizability of our findings in a sample of undergraduate students. Taken together, the studies show that explicit, but not implicit, identification with nonhuman animals predicts greater support for their rights. The implications of these findings for research on anthropomorphism and animal rights activism are discussed, as well as the limitations of these findings and possible avenues for future research.     

Dogmatisms and Catechisms — Ethics and Companion Animals

Abstract

The current reconsideration of the place in nature of human beings unfortunately continues to be an acrimonious one. All too often the debate is more akin to a warlike encounter where each side attempts to gain control or the upper hand than a search for points of agreement. Given this context, it is important to entertain views that emanate from different cultural traditions as a way to infuse the debate with new life. Students of Native American culture have consistently pointed out that the essential concepts of life balance and reciprocity represented there may serve as useful points of consideration as we struggle with the appropriate relationships with animals and nature. This article presents a representative Zuni story, told by Governor Robert E. Lewis, that illustrates these notions.     

Animals in science education—ethics and alternatives

Increasingly, moral objections are being voiced to the use or killing of animals for educational purposes, and students' opinions are reflecting this. An animal rights philosophy often underlies these objections, but many people are unaware of the logic of the animal rights position, which is often dismissed as sentimentalism or anthropomorphism. While it is now possible to take A-level biology without undertaking dissection, there are many potential undergraduate students who would like to do courses in biology, medicine, pharmacology, physiology, and nursing, but are dissuaded by the animal use involved. Such students are frequently not offered non-animal options and risk being marked down in course work and exams, even though considerable advances have been made in the development of alternative teaching aids. This article summarizes the animal rights argument, and reviews some of the alternative approaches and their teaching effectiveness.     

Abduction: Can Non-human Animals Make Discoveries?

The aim of this paper is to investigate the relationship between information and abductive reasoning in the context of problem-solving, focusing on non-human animals. Two questions guide our investigation: (1) What is the relation between information and abductive reasoning in the context of human and non-human animals? (2) Do non-human animals perform discovery based on inferential processes such as abductive reasoning? In order to answer these questions, we discuss the semiotic concept of information in relation to the concept of abductive reasoning and, more specifically, to the notion of manipulative abduction proposed by Magnani (2009). Finally, we investigate a case study of corvids’ intelligence, namely, their capacity of causal cognition.     

Selenium–Mercury Interactions in Man and Animals

Selenium–mercury interactions were most extensively studied in relation to alleviation of Hg toxicity by added selenium. This presentation considers the influence of mercury on endogenous selenium, on its tissue and cellular “status” after lifelong or acute exposure to mercury vapor (Hg^o). Discussed are data obtained from (1) humans living near or working in a mercury mine, and (2) rats experimentally exposed in the mine. Mercury vapor is unique—or similar to methylmercury—because of its ability to penetrate cell membranes and so invade all cells, where it is oxidized in the biologically active form (Hg⁺⁺) by catalase. Such in situ-generated ions can react with endogenously generated highly reactive Se metabolites, like HSe−, and render a part of the selenium unavailable for selenoprotein synthesis. Data on human populations indicate that in moderate Hg exposure combined with an adequate selenium supply through diet, Se bioavailability can be preserved. On the other hand, the results of an acute exposure study emphasize the dual role of selenium in mercury detoxification. Besides the well-known Se coaccumulation through formation of nontoxic Hg–Se complexes, we observed noticeable Se (co)excretion, at least at the beginning of exposure. The higher Hg accumulation rate in the group of animals with lower basal selenium levels can also point to selenium involvement in mercury excretion. In such conditions there is a higher probability for decreased selenoprotein levels (synthesis) in some tissues or organs, depending on the synthesis hierarchy.     

Pharmacokinetics, Tissue Distribution and Excretion of Recombinant Human Parathyroid Hormone 1–84 in Animals

To study the plasma pharmacokinetics and accumulation of the recombinant human parathyroid hormone (rhPTH) (1–84) in rhesus monkeys, and the tissue distribution and excretion profiles of ¹²⁵I-rhPTH (1–84) in rats. The concentration of rhPTH (1–84) in plasma samples were determined by an enzyme immunoassay (EIA) method after subcutaneous and intravenous bolus injection. The tissue distribution and urinary, fecal and biliary excretion patterns of ¹²⁵I-rhPTH (1–84) were investigated by trichloroacetic acid (TCA) precipitation method. Following subcutaneous (sc) administration rhPTH (1–84) in rhesus monkeys, rhPTH (1–84) exhibited rapid absorption and elimination and had no accumulated tendency after successive sc administration. Following sc administration ¹²⁵I-rhPTH (1–84) in rats, the TCA-precipitated radioactivity was widely distributed and rapidly diminished in most tissues. Approximately 83.9 and 6.8 % of the total radioactivity was recovered in urine and feces by 72 h postdosing, respectively; whereas 4.1 % excreted into bile up to 24 h postdosing. The pharmacokinetics of rhPTH (1–84) complied with linear kinetics within the examined dose range following a single sc administration had no accumulated tendency following multiple sc administration in rhesus monkeys. The accumulation of ¹²⁵I-rhPTH (1–84) in tissues/organs examined, appeared to be low in rats. The major elimination route was by urinary excretion.     

Rarity,Species Richness,and the Threat of Extinction—Are Plants the Same as Animals?

Assessment of conservation status is done both for areas or habitats and for species (or taxa). IUCN Red List categories have been the principal method of categorising species in terms of extinction risk, and have been shown to be robust and helpful in the groups for which they have been developed. A recent study highlights properties associated with extinction risk in flowering plants, focusing on the species-rich hot spot of the Cape region of South Africa, and concludes that merely following methods derived from studies of vertebrates may not provide the best estimates of extinction risk for plants. Biology, geography, and history all are important factors in risk, and the study poses many questions about how we categorise and assess species for conservation priorities.     

Vulnerable Subjects? The Case of Nonhuman Animals in Experimentation

The concept of vulnerability is deployed in bioethics to, amongst other things, identify and remedy harms to participants in research, yet although nonhuman animals in experimentation seem intuitively to be vulnerable, this concept and its attendant protections are rarely applied to research animals. I want to argue, however, that this concept is applicable to nonhuman animals and that a new taxonomy of vulnerability developed in the context of human bioethics can be applied to research animals. This taxonomy does useful explanatory work, helping to pinpoint the limitations of the 3Rs/welfare approach currently adopted in the context of animal experimentation. On this account, the 3Rs/welfare approach fails to deliver for nonhuman animals in experimentation because it effectively addresses only one element of their vulnerability (inherent) and paradoxically through the institution of Animal Ethics Committees intended to protect experimental animals in fact generates new vulnerabilities that exacerbate their already precarious situation.     

Vascular–Platelet and Plasma Hemostasis Regulators from Bloodsucking Animals

Saliva of bloodsuckers (leeches, insects, ticks, vampire bats) contains various regulators of some hemostatic stages. This review summarizes information on their structural characteristics and mechanisms of action. Most bloodsuckers are shown to inhibit vascular–platelet hemostasis by blocking collagen induced platelet adhesion/aggregation. Plasma hemostasis is inhibited by blocking activation of factor X or factor Xa directly.     

Development of the Partner’s Treatment of Animals Scale

Although studies of the relationship between animal abuse and intimate partner violence have proliferated in recent years, building upon previous work and making cross-study comparisons have been rendered difficult by the utilization of differing operationalizations of animal maltreatment within this literature. This paper aims to mitigate this problem by introducing and detailing a scale of animal maltreatment by romantic partners, developed and tested with a sample of 55 women in domestic violence shelters who self-identified as victims of intimate partner violence. The Partner’s Treatment of Animals Scale (PTAS) is comprised of five scales (emotional animal abuse, threats to harm animals, animal neglect, physical animal abuse, and severe physical animal abuse) that have strong demonstrated reliability. The construction of the scales is presented in this paper, and recommendations are made for employing the PTAS in subsequent studies.     

Bergmann’s Rule,Adaptation, and Thermoregulation in Arctic Animals: Conflicting Perspectives from Physiology,Evolutionary Biology,and Physical Anthropology After World War II

Bergmann’s rule and Allen’s rule played important roles in mid-twentieth century discussions of adaptation, variation, and geographical distribution. Although inherited from the nineteenth-century natural history tradition these rules gained significance during the consolidation of the modern synthesis as evolutionary theorists focused attention on populations as units of evolution. For systematists, the rules provided a compelling rationale for identifying geographical races or subspecies, a function that was also picked up by some physical anthropologists. More generally, the rules provided strong evidence for adaptation by natural selection. Supporters of the rules tacitly, or often explicitly, assumed that the clines described by the rules reflected adaptations for thermoregulation. This assumption was challenged by the physiologists Laurence Irving and Per Scholander based on their arctic research conducted after World War II. Their critique spurred a controversy played out in a series of articles in Evolution, in Ernst Mayr’s Animal Species and Evolution, and in the writings of other prominent evolutionary biologists and physical anthropologists. Considering this episode highlights the complexity and ambiguity of important biological concepts such as adaptation, homeostasis, and self-regulation. It also demonstrates how different disciplinary orientations and styles of scientific research influenced evolutionary explanations, and the consequent difficulties of constructing a truly synthetic evolutionary biology in the decades immediately following World War II.
